Dryer runs but does not heat; clothes remain cold and damp at the end of the cycle, no error code displayed.

Safety first: Unplug the dryer and allow it to cool fully before accessing the heater.

Checks:

• Confirm no heat: Run a short timed cycle and feel for warm air at the vent or door. If completely cold, proceed.
• Access heater: Remove the rear panel to expose the heater box and thermostats.
• Test components: With a multimeter, check continuity of the heating element, thermal cut-out, and thermostats. Replace any open components.
• Inspect wiring: Tighten or replace any loose or burnt connectors on the heater circuit.

After repair: Reassemble and test on a short cycle, monitoring for correct heating. If there is still no heat, the control board heater relay or timer contacts may be faulty and require professional diagnosis.
